Hi,
Firstly you appear to have a motor that designed for 12S operation but you wish to use it with 10S (2x5S) ?
The version of the motor you have suitable for 10S has a KV of 205 (XM6355DA-25)
Secondly there is no need to run 50C LiPo's in pattern, only adds unnecessary weight (in general as C rating increases so does battery weight) . I run, as do several others I know, Hacker 5000mA 20C batteries with no issue.
Third, as you have chosen a Dualsky motor then the Dualsky Summit 100A F3A ESC would be a good match. If you haven't already check out Juan Rombaut's YouTube channel Rombaut RC he is a sponsored Dulsky F3A flyer and has set up videos for the summit and dualsky motors, he also flies the Anthem too. He came 4th at the recent European F3a championships so he is a top flyer.
